Lourdes Sur East Barangay Hall was thought to be one of the oldest barangays among others. The late Dr. Clemente N. Dayrit Sr. wa the first person who made an action to separate Barangay Lourdes from Barrio San Nicolas. From then on they called it “Lourdes” because Dr. Dayrit and his wife were devotees of “Our Lady of Lourdes” in France. The Dayrit family donated five-hundred hectares (500 ha) of land wherein a church had been built. Two of the famous marks of the barangay are the public school situated inside the Dayrit Compound in 1912 and the ice plantation near the railroad in 1914. Dr. Dayrit had once said that this barrio will become a subdivision. This subdivision became one of the oldest in 1925 which was divided into parts: Lourdes Sur East, Lourdes Northwest, Claro M. Recto, Virgen delos Remedios, Sta. Teresita, Agapito Del Rosario, Salapungan, Lourdes Sur, and Sto Cristo. Within the 21.38 hectares of barangay Lourdes Sur East, there were 7,753 estimated people living during those times. And in 1990, 8,000 estimated people were said to be living here.
